Definitions

  • the invention relates to a hammer nut with escapement for screwing in a threaded bolt.
  • hammer nuts have roughly the outer shape of a hammer head, i.e. their extension in the plane perpendicular to the thread axis is substantially smaller in one axis than in the axis perpendicular to it.
  • This means that these hammer nuts can be effortlessly inserted into the insertion slot of components that have undercut grooves, for example rails, and then rotated 90 ° to the stop (nut-specific design), whereby they can then no longer be pulled out of the groove, because in this position the nut width is larger than the width of the insertion slot.
  • a threaded bolt is screwed into the hammer nut and is connected to a second component outside of the insertion slot mentioned. Through the screwing process, the hammer nut is pressed against the undercut of the groove, which results in a firm connection between the two components.
  • the object of the present invention is therefore to design a hammer nut with escapement so that the strength of the escapement is precisely defined and remains essentially the same over several screwing operations, that there is no adverse effect on the environment and that the nut can nevertheless be produced at a reasonable cost.
  • three solutions to this problem are provided, namely the first solution characterized in claim 1, the second solution characterized in claim 5 and the third solution characterized in claim 9.
  • the invention also specifies a production method for each of these solutions.
  • FIG. 1 shows, as mentioned, a hammer nut in side view and in plan view.
  • the extension of the nut in one direction is designated by a, where a is smaller than the width of the insertion slot of the undercut groove into which the nut 10 is inserted should, the extension in the other, perpendicular direction is denoted by b, where b is substantially larger than the width of the insertion slot, so that the surfaces 10b of the nut 10 represent stop surfaces for contact with the undercut of the groove mentioned.
  • Fig. 2 shows a sketch of part of the thread of the nut 10 according to the first embodiment of the invention.
  • the arrow shows the direction from which a threaded bolt should be screwed into this nut. It can be seen that seen in the screwing direction of the threaded bolt, the last two threads of the nut 10 are not fully formed, that is, the diameter d 1 of the thread base is smaller than the diameter d 2 of the preceding, fully formed threads.
  • This thread is expediently produced by means of a tap 20, the two threads of which are adjacent to the tip of the drill bit are ground somewhat. However, it is important that the tap 20 after cutting the thread in the opposite direction of rotation again Nut is unscrewed.
  • ribs 30 protrude from the thread flanks of the last two thread turns, as can be clearly seen from the drawing. These ribs act similarly to the incomplete shaping of the last two to three threads of FIG. 2, ie when the threaded bolt is screwed in there is an inhibition when the last two threads are reached that leads to a correct fixation of the nut / rail connection, which cannot be loosened by vibrations either. To give a clue here, too, it should be stated that the ribs protrude about 0.05 mm beyond the thread flanks, again based on a standard nut M6.
  • the production of the ribs 30 in the nut thread takes place in such a way that grooves are cut or milled into the screw tap that cuts the nut thread, namely into the two threads adjacent to the drill tip.
  • the depth of the grooves depends on the desired height of the ribs in the nut thread.
  • the tap 21 must be unscrewed from the nut in the opposite direction after the thread has been cut, because otherwise the subsequent, non-grooved threads of the drill 21 would cut away the resulting ribs or the tap 21 would get stuck in the nut 10.
  • Fig. 4 finally indicates the third embodiment of the invention.
  • the pitch of the nut thread deviates slightly from the pitch of the standard thread of the screw bolt, namely over the entire thread length of the nut 10. The difference may understandably not be too great.
  • the pitch offset of the nut thread should be approximately + 2% or - 2% compared to the standard thread and thus compared to the thread of the threaded bolt.
